Title: Improvements in or relating to hollow glass bodies
IPC: C03B25/02
Filed: 1958-07-25
Abstract: 830,733. Hollow glass ware. GLACES DE BOUSSOIS. July 25, 1958 [July 30, 1957], No. 24042/58. Class 56. Hollow glass ware, e.g. bottles, jars and beakers, of small wall thickness and high mechanical strength is made by a process which comprises bringing the walls of a hollow glass body having an orifice leading to the interior to a temperature at which the viscosity of the glass is below 109 poises, cooling the glass from the outside while maintaining the mean viscosity between 10<SP>9</SP> and 1012 poises, and blowing the walls with a gas whose temperature is at least equal to that of the internal surface of the glass and finally solidifying the walls by cooling from the outside. The hollow glass body is given its temporary form by the " press-and-blow " or " blow-and-blow " method. Any annealing is confined to the region near the orifice. Fig. 2 shows a jar 1, which has previously been heated by radiation in a chamber, surrounded by the mould 18 composed of a thick inner envelope 19 and a sheet-metal outer envelope 20 which is provided with passages 21 and 22 for admitting and discharging cooling gas supplied through nozzles 23 to act on the outside of the jar. The thermal conditioning is immediately followed by the admission of hot high-pressure gas to the interior of the jar by means of blowing-head 24 and duct 25. The rapid solidification of the glass may be effected by conduction of heat from the mould lining or by an arrangement (not shown in Fig. 2) whereby the expansion of the glass triggers off a fresh supply of cooling gas. In each case it is the outer layer which solidifies first, whereafter solidification progresses rapidly through the glass thickness to the inner layer. The inner surface of the mould should be of high reflecting power, e.g. stainless steel, gold, platinum, gold-platinum alloy or powdered titanium oxide.

Abstract: 499,053. Toothed gearing; rangefinders. BARR & STROUD, Ltd., and EMETT, (nÚe STROUD), L. E., STROUD, (nÚe MURRAY), L. M. V., STROUD, C. J. R., and STROUD, A. W., [Representatives of STROUD, W.]. Sept. 6, 1937, No. 24252. [Class 80 (i)] [Also in Group XX] Relates to apparatus for the conversion of motion according to one law into motion according to another law. Such apparatus, which may be employed for the conversion of the motion of the working head of a constant base range-finder into motion proportional to the changes of range, is described in Specification 133,974, [Class 80 (i)]. This comprises two helico-spiral gears each rotatable about its own axis and geared together by a toothed idler wheel capable of movement in two directions, viz. : in the direction of and at rightangles to its axis. The transverse movement was obtained by means of a slide. According to the invention, the transverse movement is an angular pivotal movement. The gear A, Fig. 1, rotates about its own axis ; the gear B similarly rotates and in addition is movable axially by a screw 2. The interconnecting idler wheel C is carried by an arm 3, Fig. 4, carried by a sleeve 6 turning and slidable on a guide rod 5. Through an aperture 7 in the arm 3 passes a nut 9 having projections 10 engaging the sleeve. Rotation of a screw 8 causes axial movement of the wheel C. In Fig. 5, the idler wheel C is mounted on an arm 11 having a sleeve 12 internally screw-threaded for a short distance at its right-hand end only, the sleeve fitting over a rod 13, the right-hand part of which is screw-threaded to engage the sleeve, the lefthand part being plain. The rod 13 is rotated by gear-wheels 14, 15 to provide the necessary axial movement to keep the gears in mesh, the sleeve turning on the rod to give the swinging movement to the idler. With such swinging movement the sum of the radii of the helico-spiral members at the points of meshing with the idler wheel need not be constant. Both of the helico-spiral members may move longitudinally, instead of one as in the Specification referred to.
